CNET: Crazy-looking smartphones

The good: The Motorola Moto X squeezes a speedy camera and futuristic voice command capabilities into a well-crafted design that hits the sweet spot between screen size and comfort. The phone has great battery life and is available in an endless variety of customized designs.

The bad: With no expandable storage, space could get tight, especially on the 16-gigabyte base model. The screen isn't as big and sharp as those on some competing handsets.

The cost: $0 (with 2-year contract) to $430.62 (unlocked)

The bottom line: Although the screen quality and storage capacity lag behind rival super phones, the Moto X's superbly compact and comfortable design, whiz-bang voice controls and long battery life make it an Android contender.

CNET rating: 4 stars out of 5 (Excellent)

LG G Flex

The good: The LG G Flex's contoured display renders media watching more engaging, it features a scratch-resistant coating and its sizable battery provides an adequate amount of juice.

The bad: The G Flex's massive size can be unwieldy, its camera quality is mediocre, and its 720p display can't outpace its competitors.

The good: The Amazon Fire Phone has cool 3D-like visuals and a fresh OS design, and it hits the sweet spot for one-handed operation. It has deep, convenient integration with Amazon services.

The bad: Although it costs the same (or more) as competing Android and iPhone models, the Fire Phone delivers a less extensive app store and service experience and more sluggish performance. Battery life is disappointing.

The cost: $199.99 (with 2-year contract) to $699.00

The bottom line: Despite its daring aspirations and 3D-like party tricks, the brave, new Fire Phone's lack of Google services will alienate anyone who expects the flexibility of a modern Android phone.
